At least once a year, visually inspect the protection The table below shows this frequency, as originally devices (valves, pressure switches). published in the regulation. Check whether an inspection frequency is also set by other regulations or standards applicable to your system (e.g. EN 378, ISO5149, etc.). If the machine operates in a corrosive environment, inspect the protection devices more frequently.
